"Janet Tweedy" wrote in message ... In article , Mike Lyle writes I don't know of any ill-effect on plants of glyphosate residue at root level. Not even the URL above claims any such effects. Negligible effect in soil unless you vastly overdose it. You pretty much have to hit green plant material with glyphosate for it to be effective. As one who is currently suffering from an overload of caustic remarks after recommending, in innocence, a Roundup container, (I was recommending the container which allows you to fill a small plastic gun/nozzle via a plunger and then spray rather than the chemical therein) I can sympathise! I don't like paying for fancy packaging. But there is nothing wrong with glyphosate - considering how deadly it is to green plants it is astonishingly benign in animals. The wetting agents used in the commercial formulations are worse. However I used a flame gun to go along the bottom of hedges, especially in the damp or in the winter when my hawthorn doesn't have leaves. The gun is not intended to burn up the foliage but rather to heat treat it and it will die, then you go along a couple of weeks later and redo it and the foliage will burn up easily,. Hmm. This isn't such a good idea with a conifer hedge. The pine resin makes them very inclined to catch fire. ISTR Bob Flowerdew has a tale about burning down a large conifer hedge he was supposed to be weeding with a flamethrower. Is it a 'parosene' butane fuelled 'gun'? If so, there have been opinions voiced here that it is next to useless. Personally, I disagree, but anyone thinking of buying one might like to be aware of the negative feedback on this group before shelling out. I still reckon spot weeding with glyphosate is easy enough under hedges. You just have to be careful. And the odd spec on a big tree sized plant won't easily kill it. Cut off any parts accidentally exposed. Amazingly waxy holly seedlings seem to be able to tolerate a direct hit. But don't rely on this! Buttercup is also somewhat tolerant. Regards, Martin Brown |
